Abstract
Description
Technical Field
[0001] This application relates to the field of soil covering and compaction technology, and more particularly to a crushing soil covering and compaction device for barley seeds. Background Technology
[0002] Barley is a highly adaptable crop with a wide range of cultivation methods. Trench planting is a common planting method with many benefits, such as drought prevention, water retention, heat preservation, and easy fertilization. The process is as follows: trenches are dug in the cultivated land, barley seeds are evenly sown in the trenches, and then the barley seeds are covered with soil. Covering the seeds with soil not only protects them from wind, birds, and other animals, reducing seed loss, but also maintains soil surface moisture and soil warmth, creating a good environment for seed germination and ensuring normal seed growth.
[0003] However, due to severe soil compaction in some areas, and because compacted soil has poor aeration and water retention, directly covering seeds with compacted soil can easily hinder the contact between seeds and air and moisture, affecting normal seed germination. Furthermore, even if the seeds can germinate, the compacted soil will restrict the growth space of the seedlings, leading to limited root development and thus affecting the overall health of the crop.
[0004] Adopting reasonable farming practices can help alleviate soil compaction. For example, tilling and applying soil conditioners can improve soil quality and alleviate the problem of soil compaction to a certain extent. However, soil compaction is also closely related to the texture of the soil itself. The stronger the soil's viscosity, the more likely it is to compact.
[0005] Currently, commonly used soil covering devices typically consist of two baffles. By combining the two baffles into a funnel-shaped structure, the soil from both sides of the seed furrow is gathered into the seed furrow for soil covering. However, this method of soil covering is difficult to solve the problem of soil clumping, resulting in a large amount of clumped soil in the soil covering layer. This hinders seed growth after soil covering and affects crop yield. Summary of the Invention
[0006] To address or partially address the problems existing in the related technologies, this application provides a crushing and compacting soil covering device for barley seeds. This device can collect, sieve, and crush clumps of soil, and cover the seeds with a double layer of soil. The lower layer is fine-grained soil to retain moisture and warmth for the seeds, providing a warm and humid environment, while the upper layer is large-grained soil to reduce the impact of wind and water erosion on the soil.

The groove is also threadedly connected to fixing bolts for fixing the position of the adjustment plate.
[0012] Optionally, in some embodiments of the first aspect, the covering plate has an arrowhead-shaped structure, with its tip pointing in the direction of extension of the planting furrow.
[0013] Optionally, in some embodiments of the first aspect, the pressing assembly includes a column, a pressing rod, a tension spring, a wheel frame, and a pressing wheel. The column is fixed vertically on the slider, and a pressing rod is hinged to the top of the column. A pressing wheel is mounted on the end of the pressing rod via the wheel frame. A tension spring is also provided between the column and the pressing rod, which allows the pressing wheel to always remain close to the ground.
[0014] Optionally, in some embodiments of the first aspect, the wheel frame is provided with a placement rod, and counterweight wheels of different weights can be placed at the placement rod according to the required pressure. The end of the placement rod is also provided with a threaded hole, and a fixing plate for fixing the counterweight wheel is installed at the threaded hole. The frame is provided with a connecting frame, and a connecting rod is fixedly connected to the connecting frame. The end of the connecting rod is hinged to the rear of the tractor, so that the frame can be rotated and lifted along the hinge. A telescopic rod for controlling the rotation angle of the frame is also provided between the connecting frame and the tractor.
[0015] Optionally, in some embodiments of the first aspect, the feeding mechanism includes a second adjusting rod, a second sliding rod, a shovel plate, and a guide plate.

The shovel plate is installed at an incline at the bottom of the second sliding rod. The shovel plate is provided with guide plates corresponding to the soil piles on both sides of the planting furrow.
[0016] Optionally, in some embodiments of the first aspect, a retaining mechanism for preventing soil piles from sliding into the seed trench is further installed in front of the feeding mechanism. The retaining mechanism includes a first adjusting rod, a first sliding rod, a mounting frame, and a retaining plate. The first adjusting rod is fixedly installed vertically on the frame, and a first sliding rod is slidably connected inside the first adjusting rod. A retaining plate corresponding to the soil piles on both sides of the seed trench is rotatably installed at the bottom of the first sliding rod through the mounting frame.
[0017] The technical solution provided in this application may include the following beneficial effects:
[0018] This application utilizes a feeding mechanism to collect soil piles on both sides of the seed furrow. A mesh belt conveyor then screens the soil, allowing fine-grained soil to fall directly into the furrow for initial covering. This fine-grained soil helps retain moisture and warmth for the seeds, providing a warm and humid environment. A crushing mechanism breaks up clumps of soil, creating large clods for secondary covering. Covering the fine-grained soil with these large clods not only helps mitigate wind and water erosion and maintain soil structure and moisture, but also breaks down the soil structure, reducing the likelihood of compaction, as fine-grained soil is prone to hardening under humid conditions. This looser soil facilitates seed penetration and root expansion, ensuring normal seed growth.

[0042] See Figure 1When digging the seed furrow 8, the excavated soil is usually piled on both sides of the furrow 8 to form a mound 81. This application provides a crushing and compacting soil covering device for barley seeds, including a frame 1, a mesh belt conveyor 2, a crushing mechanism 3, a compacting mechanism 4, and a feeding mechanism 7. Wheels 11 are installed on both sides of the frame 1 to facilitate the movement of the frame 1 by a tractor. A feeding mechanism 7 for collecting the mound 81 containing clumps of soil is installed at the front end of the frame 1, and a mesh belt conveyor 2 for screening the soil is installed on the frame 1. The fine soil particles screened by the mesh belt conveyor 2 are used to initially cover the seeds in the seed furrow. The fine soil particles help retain moisture and warmth for the seeds, providing a warm and humid environment to ensure normal seed growth. The discharge end of the mesh belt conveyor 2 is connected to... The crushing mechanism 3 breaks down clumps of soil into large clods, which are then used to cover the seeds in the seed furrow 8 with a second layer of soil. Covering the fine-grained soil with a layer of large clods not only helps to mitigate wind and water erosion and maintain soil structure and moisture, but also breaks down the soil structure, reducing the possibility of compaction, as fine-grained soil is prone to hardening under moist conditions. This makes the soil looser, facilitating seed penetration and root expansion, thus ensuring normal seed growth. At the tail end of the frame 1, a compaction mechanism 4 is also provided to compact the soil covering. The compaction mechanism 4 can tighten the soil covering layer, ensuring close contact between barley roots and soil, promoting root development, enhancing the ability to absorb nutrients and water, and providing a stable foundation to enhance lodging resistance.
[0043] In some embodiments, see Figure 2 The frame 1 has a rectangular structure, with a vertically arranged connecting frame 5 welded to its front end. The connecting frame 5 has two layers, with a connecting rod 51 welded horizontally to the lower layer. The end of the connecting rod 51 is hinged to the rear of the tractor, allowing the frame 1 to rotate and lift around the hinge. A telescopic rod 52 is hinged to the upper layer of the connecting frame 5, with its other end also hinged to the rear of the tractor. In use, by controlling the telescopic rod 52 to retract, the connecting rod 51 can rotate around the hinge, thereby lifting the frame 1, facilitating changes in the work area and preventing the device from colliding with hard ground during transfer. During use, the telescopic rod 52 is in a shortened state while the tractor is moving, and the frame 1 is raised off the ground. When the tractor is at the end of the planting furrow 8, ready for soil covering and compaction, the telescopic rod 52 is extended, lowering the frame 1 and setting the device at the planting furrow 8, ready for soil covering and compaction. The telescopic rod 52 can be an electric telescopic rod or a hydraulic cylinder.
[0044] In some embodiments, see Figure 3An installation rod 12 is welded to the front end of the frame 1. The installation rod 12 is divided into front and rear ends. The front end is equipped with a soil retaining mechanism 6, and the rear end is equipped with a feeding mechanism 7. The feeding mechanism 7 includes a second adjusting rod 71, a second sliding rod 72, a soil scraper 73, and a guide plate 74. The second adjusting rod 71 is fixedly welded to the rear end of the installation rod 12 vertically. The second sliding rod 72 is slidably connected inside the second adjusting rod 71. The soil scraper 73 is installed at an incline at the bottom of the second sliding rod 72. One end of the soil scraper 73 is flush with the soil surface, and the other end is connected to the feeding end of the mesh belt conveyor 2. The soil scraper 73 is equipped with guide plates 74 corresponding to the soil piles 81 on both sides of the planting ditch. During use, as the tractor drives the frame 1 forward, the soil pile 81 is continuously scooped up by the shovel plate 73 and guided into the mesh belt conveyor 2 through the guide plate 74. If the guide plate 74 is not set, since the middle position of the shovel plate 73 is above the planting furrow 8, there is no soil in front of the shovel plate 73 to provide thrust to push the soil to the mesh belt conveyor 2. In order to prevent the soil from slipping from the middle position of the shovel plate 73 into the planting furrow 8, four guide plates 74 are set on the shovel plate 73, in pairs to form a guide channel, which facilitates pushing the soil to the mesh belt conveyor 2. In use, as the tractor drives the device forward, the shovel plate 73 continuously scoops up the soil pile 81. Guided by the guide plate 74, the soil falls into the feed end of the mesh belt conveyor 2. The conveyor belt of the mesh belt conveyor 2 has evenly spaced mesh 21 openings, and side plates 22 are provided on both sides to prevent soil from spilling from the sides. As the mesh belt conveyor 2 operates, fine soil particles pass through the mesh 21 and fall into the planting furrow 8, while clumps of soil are transported to the crushing mechanism 3 for crushing. Furthermore, to facilitate adjustment of the shoveling volume, a threaded hole is provided at the bottom of the second adjusting rod 71, and multiple through holes corresponding to the threaded hole are vertically opened along the upper edge of the second sliding rod 72. By aligning the through holes at different heights with the threaded holes and then fixing them with bolts, the height of the shovel plate 73 can be adjusted. When the required soil intake is small, the position of the shovel plate 73 is raised; when the required soil intake is large, the position of the shovel plate 73 is lowered.
[0045] In some embodiments, see Figure 3During the soil-shoveling process, the soil will disperse to the left and right sides of the shovel plate 73 due to resistance. If not handled, some of it will slide into the planting trench 8, affecting subsequent covering operations. Therefore, a soil-blocking mechanism 6 is installed at the front end of the feeding mechanism 7. The soil-blocking mechanism 6 includes a first adjusting rod 61, a first sliding rod 62, a mounting frame 63, and a soil-blocking plate 64. The first adjusting rod 61 is fixedly welded to the front end of the mounting rod 12 vertically, and the first sliding rod 62 is slidably connected inside the first adjusting rod 61. The mounting frame 63 is fixedly connected to the bottom of the first sliding rod 62, and the soil-blocking plates 64 corresponding to the side walls of the planting trench 8 are rotatably connected to the left and right sides of the mounting frame 63. In use, the soil-blocking plates 64 block the soil that disperses to one side of the planting trench 8, ensuring the smooth progress of subsequent covering operations. Furthermore, to facilitate adaptation to planting trenches 8 at different depths, a threaded hole is provided at the bottom of the first adjusting rod 61, and multiple through holes with corresponding threaded holes are provided vertically along the upper edge of the first sliding rod 62. By aligning the through holes at different heights with the threaded holes and then fixing them with bolts, the height position of the retaining plate 64 can be adjusted to meet the usage requirements of planting trenches 8 at different depths.
[0046] In some embodiments, see Figure 4-6 The crushing mechanism 3 includes a crushing bucket 31, a crushing roller 32, a first crushing tooth 33, a second crushing tooth 34, and a motor 35. The crushing bucket 31 is fixedly installed on the frame 1 and corresponds to the discharge end of the mesh belt conveyor 2. The crushing roller 32 is rotatably installed at the bottom of the crushing bucket 31. The first crushing tooth 33 is evenly arranged on the crushing roller 32. The motor 35 for driving the crushing roller 32 is installed on the outside of the crushing bucket 31. The motor 35 can drive the crushing roller 32 to rotate, thereby crushing the clumped soil. Furthermore, a second crushing tooth 34 is provided on the inner wall of the crushing bucket 31. The first crushing tooth 33 and the second crushing tooth 34 are staggered and there is a gap between the first crushing tooth 33 and the second crushing tooth 34. This can break up the clumps of soil into large soil clods for secondary covering. Covering fine soil with a layer of large soil clods can not only help alleviate wind and water erosion and maintain soil structure and moisture, but also reduce the possibility of soil compaction because fine soil is prone to compaction under humid conditions. Large soil clods can break up the soil structure, making the soil looser and facilitating seed penetration and root expansion, thereby ensuring normal seed growth.
[0047] In some embodiments, see Figure 7 The compaction mechanism 4 includes a crossbar 41, a slider 42, a soil cover thickness adjustment component 43, a compaction component 44, and a locking bolt 45. The crossbar 41 is fixed to the tail of the frame 1. The slider 42 is slidably connected to the crossbar 41, and the slider 42 is threadedly connected to the locking bolt 45. The position of the slider can be fixed by tightening the locking bolt 45. The soil cover thickness adjustment component 43 and the compaction component 44 are also installed on the slider 42.
[0048] The soil covering thickness adjustment component 43 is used to adjust the soil covering thickness. It includes an adjustment plate 431, a soil covering plate 432, and a fixing bolt 434. The slider 42 has a groove 433 on its side. The adjustment plate 431 is vertically slidably connected to the groove 433, and the soil covering plate 432 is fixedly connected to the bottom of the adjustment plate 431. The groove 433 is also threadedly connected to the fixing bolt 434 for fixing the position of the adjustment plate 431. In use, according to the required soil covering thickness, the adjustment plate 431 is slid to adjust the distance between the soil covering plate 432 and the ground of the seed furrow 8. When the soil covering thickness is greater than this distance, as the soil covering plate 432 moves forward, the excess soil will be pushed to the left and right sides of the seed furrow 8, thereby avoiding an excessively thick soil layer covering the seeds and affecting seed growth. Furthermore, to facilitate pushing the excess soil to the sides, the soil covering plate 432 has an arrow-shaped structure, with its tip pointing in the direction of extension of the seed furrow 8.
[0049] In some embodiments, see Figure 8 The compaction assembly 44 includes a column 441, a compaction rod 442, a tension spring 443, a wheel frame 444, and a compaction wheel 445. The column 441 is fixed vertically to the top of the slider 42, and the compaction rod 442 is hinged to the top of the column 441. The compaction wheel 445 is installed at the end of the compaction rod 442 through the wheel frame 444. A tension spring 443 is also provided between the column 441 and the compaction rod 442. The tension spring 443 can keep the compaction wheel 445 close to the ground, ensuring that the compaction wheel 445 will not bounce continuously due to the rugged soil surface during operation, thus improving its stability. At the same time, it also provides a certain compaction force for the compaction wheel 445.
[0050] Furthermore, since different soil types require different compaction forces, a placement rod 446 is provided on the wheel frame 444 to provide multiple compaction force options. Depending on the required compaction force, counterweight wheels 447 of different weights can be placed at the placement rod 446. The weight of the counterweight wheels 447 further provides compaction force to the compaction wheel 445. A threaded hole is also provided at the end of the placement rod 446, and a fixing plate 448 for fixing the counterweight wheels 447 is connected to the threaded hole by threads.
[0051] Specific work process:
[0052] The device is installed at the rear of the tractor. During transfer, the telescopic rod 52 is shortened to lift the frame 1 off the ground, preventing damage from impacts during the transfer. During operation, the telescopic rod 52 is extended to lay the frame 1 flat on the seed furrow 8. As the tractor moves forward, the shovel plate 73 continuously shovels up the soil piles 81 on both sides of the seed furrow 8. During the shoveling process, the soil retaining mechanism 6 prevents the soil from sliding into the seed furrow 8. The shoveled soil enters the mesh belt conveyor 2. Fine soil particles pass through the mesh 21 and fall into the seed furrow 8 for the first covering of the seeds. The clumps of soil are transported along the mesh belt conveyor 2 to the crushing mechanism 3 to be crushed into large soil clods for the second covering of the seeds. After covering, the soil plate 432 pushes the excess soil to the left and right sides of the seed furrow 8 to prevent the soil covering the seeds from being too thick. The soil layer is then compacted by the compaction wheel 445 to complete the covering and compaction operation.
[0053] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
[0054] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
